Fun stuff. Played it a bit more than I expected. There's only 2 levels right? When the combat loop was really going, it was quite engaging. Especially when I was running out of block and planning my escape to heal. The down side ended up being that usually I just dodge or kill them quick instead of using strategic blocking - but that could be tuned up nice.
Other little things: Clicking to shoot when mouse doesn't aim was kinda counter intuitive (Gamepad is probably the way to play). Also, the fact that you can't shoot diagonal when still but can shoot in the cardinal directions while standing still was a bit counter intuitive (although I see that telegraphing stationary facing would mean producing twice as much player art).
Good job.
